[0002] Automotive inspection fixtures are specialized inspection equipment used to measure and evaluate the dimensional quality of automotive parts. They enable online inspection of parts at the production site, and their measurement accuracy directly affects the overall vehicle assembly quality.

[0003] By accurately installing parts on the inspection fixture, and using tools such as measuring instruments and calipers to inspect the surface and periphery of the parts, and by using inspection pins or visual inspection to visually inspect holes of different types on the parts and the connection positions between parts, the quality status of the parts can be quickly determined.

[0004] Because automotive sheet metal parts such as car doors and hoods have springback after stamping, it is necessary to strictly test the radius of curvature and bending angle. The wire gauge can test the curvature of the sheet metal parts to determine whether the curvature and bending angle of the sheet metal parts meet the requirements. However, when checking the tension of the wire, the gauge needs to be disassembled and adjusted in a cumbersome manner. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a cable tensioning mechanism for automotive inspection fixtures, thereby resolving issues such as cumbersome adjustment procedures when adjusting the tension of the cable tensioning fixture in the prior art.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] Example 1: This utility model provides a car inspection tool cable pulling mechanism, including a mounting base 1, a through placement hole 2 inside the mounting base 1, an adjustment hole 3 on the top of the mounting base 1, and a detachably connected mounting disc 4 and a mounting disc 5 at the front and rear ends of the mounting base 1. The mounting disc 4 has annularly distributed wire rings 6, and a guide mounting rod 7 is provided between the mounting disc 4 and the mounting disc 5. A cable pulling disc 8 is rotatably connected on the guide mounting rod 7. The wire harness passes through the wire rings 6 and is fixed on the cable pulling disc 8. A detachably connected push-pull member 9 is provided on the outer wall of the mounting disc 5, and the push-pull member 9 is connected to the guide mounting rod 7.

[0026] It should be noted that the mounting base 1 is equipped with mounting disc 4 and mounting disc 5 connected by screws. The wire harness passes through mounting disc 4 and is fixed to the pull plate 8. The push-pull component 9 is connected to mounting disc 5 by threads and is also connected to the guide mounting rod 7. The top of the mounting base 1 is provided with an adjustment hole 3. When it is necessary to adjust the tension of the wire harness, the tension of the wire harness on the pull plate 8 can be adjusted directly by inserting a tool into the adjustment hole 3.

[0027] When the wire harness is not visible from the adjustment hole 3, the push-pull component 9 can be rotated to loosen it from the mounting plate 2 5. Then, the guide mounting rod 7 can be rotated to pull the wire harness 8 to adjust the wire harness to the appropriate position. After that, the wire harness can be adjusted through the adjustment hole 3. This avoids the need to disassemble the entire fixture and improves the flexibility of adjusting the wire harness tension.

[0028] In this embodiment, the vertical cross-sectional profile of the adjustment hole 3 is "T" shaped. The bottom of the horizontal section of the "T" shaped adjustment hole 3 is provided with a magnetic strip 10. The adjustment hole 3 is provided with a sealing block 11. The bottom of the sealing block 11 is symmetrically provided with a magnetic strip 12 that attracts the magnetic strip 10.

[0029] It should be noted that by designing the adjustment hole 3 as a "T" shape, the sealing block 11 and the adjustment hole 3 cooperate with each other, so that the sealing block 11 will not fall out of the adjustment hole 3. The sealing block 11 and the adjustment hole 3 are attracted to each other by magnetic strip 10 and magnetic strip 12, so that the sealing block 11 can be attracted into the adjustment hole 3, which is simple and convenient.

[0030] In this embodiment, the top surface of the sealing block 11 is flush with the top surface of the mounting base 1, and the top of the front and rear ends of the sealing block 11 is provided with grooves 13. The top of the mounting base 1 and the sides of the sealing block 11 are engraved with switch markings 14.

[0031] It should be noted that the top surface of the sealing block 11 is designed to be flush with the top surface of the mounting base 1 to prevent the sealing block 11 from protruding from the mounting base 1, so that it remains as a whole with the mounting base 1, improving the aesthetics. The switch mark 14 can be set to facilitate the user to control the tension and looseness of the wire harness.

[0032] In this embodiment, the diameters of mounting disc 4 and mounting disc 5 are larger than the diameter of placement hole 2. Mounting disc 4 and mounting disc 5 are locked onto mounting base 1 by screws. Guide disc 15 is provided on the opposite side of mounting disc 4 and mounting disc 5, and guide disc 15 cooperates with placement hole 2.

[0033] It should be noted that the diameters of mounting disc 4 and mounting disc 5 are larger than the diameter of placement hole 2 to prevent mounting disc 4 and mounting disc 5 from entering the mounting base 1. Guide discs 15 are provided on mounting disc 4 and mounting disc 5. The guide discs 15 cooperate with placement hole 2 to position the guide hole 16 and also facilitate locking mounting disc 4 and mounting disc 2 onto mounting base 1.

[0034] In this embodiment, the middle of the mounting plate 4 and the guide plate 15 is provided with a through guide hole 16, and the periphery of the guide hole 16 is provided with wire rings 6 arranged in a ring for the wire harness to pass through.

[0035] It should be noted that, through the guide hole 16, the guide mounting rod 7 will pass through the guide hole 16 during forward movement, thereby improving the stability of the guide mounting rod 7 during movement. A wire ring 6 is provided in a ring around the guide hole 16 for the wire harness to pass through, which can better allow the wire harness to pass through the wire ring 6 and enter the mounting base 1.

[0036] In this embodiment, the rotation of the cable pull plate 8 is restricted by the guide mounting rod 7. The cable pull plate 8 is provided with wire harness fixing holes 18 arranged in a ring. The outer ring wall of the cable pull plate 8 is provided with locking holes 19 that communicate with the wire harness fixing holes 18.

[0037] It should be noted that the cable pull plate 8 can rotate on the guide mounting rod 7, but its position is limited so that it can only rotate but not move. After the wire harness passes through the wire ring 6, the cable pull plate 8 can be rotated so that the wire harness fixing hole 18 can correspond to the hole of the wire ring 6. Later, the tension of the wire harness can also be adjusted by adjusting the adjustment hole 3 when the cable pull plate 8 is rotated.

[0038] In this embodiment, the guide mounting rod 7 is provided with a threaded mating hole 20 on the side near the push-pull member 9, the push-pull member 9 is provided with a threaded part 21 that mates with the mounting plate 5 on the side near the mounting base 1, and a threaded rod 22 that mates with the threaded mating hole 20 is provided on the side of the threaded part 21 away from the push-pull member 9.

[0039] It should be noted that a threaded mating hole 20 is provided at one end of the guide mounting rod 7, and the threaded rod 22 is mated with it, so that the guide mounting rod 7 and the push-pull component 9 are designed to be detachable. The push-pull component 9 adopts a push-pull clamp method. The push-pull clamp is existing technology and will not be described in detail. During the back-and-forth pulling of the push-pull clamp, the guide mounting rod 7 can be moved to achieve back-and-forth displacement. The cable tray 8 is installed on the guide mounting rod 7, and the wire harness is fixed on the cable tray 8, so that the wire harness can move back and forth, and the tension and looseness can be controlled.

[0040] The push-pull component 9 and the mounting plate 2 5 are also designed with a threaded connection. After loosening, they can drive the guide mounting rod 7 to rotate together, so that the wire harness to be adjusted can be rotated to the bottom of the adjustment hole 3 as needed.

[0041] In this embodiment, the mounting plate 2 5 is provided with wire holes 17 arranged in a ring.

[0042] It should be noted that the mounting plate 2 5 is provided with a ring of wire holes 17. The wire harness will pass through the wire harness fixing hole 18 and be fixed on the pull plate 8. When it continues to extend after passing through the wire harness fixing hole 18, it can be led out from the wire hole 17 to avoid it from being intertwined with other wire harnesses inside the placement hole 2.

[0043] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
